"The lack of indexes for the FK's will cause a share lock to be taken out on the child table when ever the parent is deleted or updated." The most recent Oracle class I took said that in 9i, this lock on the child
table is taken and released immediately. Supposedly to speed the process up
a bit.


I did consider that this might have changed in 9i.

The posted didn't mention a version, so I didn't pursue it.

Have you tested to see if this is what happens in 9i?

Jared
